The following options are currently supported:
(1) model_filename (string): The filename to load the translated program of target Layer.
Default filename is :code:`__model__` .
(2) params_filename (string): The filename to load all persistable variables in target Layer.
Default file name is :code:`__variables__` .

If True, each parameter will be loaded from a file separately, the file name is the parameter name,

(4) keep_name_table (bool): Configures whether keep ``structured_name -> parameter_name`` dict in
